Change the Date format to the one you prefer (I like “Year-Month-Day”)

Click the “Update” button at the bottom of the page

Advanced Settings:
The following settings should be set to connect to the DFR:

SIP Server: sip.dfrvoip.org.uk

Outbound Proxy: sip.dfrvoip.org.uk

SIP User ID: yourDFRusername

Authenticate ID: yourDFRusername

Authenticate Password: yourDFRpassword

Scroll down a bit, then…

Use random port: Set to “yes”

NAT Traversal: Set to “no”

Send DTMF: Set to “via RTP (RFC2833)”

NTP Server: uk.pool.ntp.org

Once you’ve done the above, hit the “save” button at the bottom of the page, then click the “advanced settings” link on the confirmation page, scroll down to the bottom of the page again and click the “reboot” button.

Your phone should now show the right date/time and if you pick the handet up you should get dialtone. If you don’t get dialtone, go back through the settings and check them all.

Optional Settings:
The following settings are optional, but “nice to have”

Admin Password: I recommend changing this from “admin” and either carefully note the password, or set it to something like the mac address of the phone.
